Abstract: An injection mould for shaping plastic materials, in particular an injection mould for synthetic materials, has a hot-runner block (at 11). The hot-runner block (at 11) has on at least one broad face (B) at least one receiving groove (20) for in each case a pipe-heating element (18). Quick installation of a pipe-heating element (18) without requiring any finishing while maintaining good heat transfer properties is achieved by the pipe-heating element (18) being compressed within the receiving groove (20) and its thereby deformed pipe outer wall (23) held pressed against the groove inner face (at 25). <IMAGE>

Inventor: LARSON BRENT D
IPC: G11B7/24067
Filed: 1990-10-29
Abstract: Apparatus incorporating a liquid crystal cell which includes first and second substrates defining opposite sides of the cell is described for recording information. A layer of a liquid crystal material of a smectic-A type is disposed between the substrates. The cell is designed to create a birefringent effect in the liquid crystal material, whereby polarized light of a wavelength other than a first wavelength has the polarization of the light rotated by passing the written areas of the liquid crystal material. This rotation is caused by a homogeneous alignment of the liquid crystal molecules wherein the molecules are oriented substantially parallel to themselves and the plane of the substrates. Such effect may be achieved by employing a thickness of the liquid crystal material significantly below conventional values.

Abstract: The invention relates to a digital processor with a pipelined architecture using a loop control method permitting programming "do loops" having no in-loop overhead processing cycle requirement. It is implemented utilizing three hardware registers (18, 19, 20) and control logic circuits that contain the parameters controlling the limits of number of iterations for the process loop being executed. The three control registers (18, 19, 20) constitute a sharable resource that can be used in an interrupt-driven, concurrent task processing architecture that provides for the programming loop control parameters to be stored in software, each software task having its own associated and dedicated loop control parameters. The single set of control registers are loaded or saved and restored from memory, thus maintaining a sharable control resource for utilization by numerous processing tasks. Multiple applications may be processed concurrently with the loop control parameters being shifted into and out of the registers from and to data memory to preserve them in dedication to their own process tasks.
